Hi linq936,

Hi linq936, i have extracted from the iRule list of commands, the ones that are TCL commands, and here after the list of them. all the other commands like client_side for example, are F5 provided commands, but not TCL.

 

So here after, the list:

 

 

tell

 

subst

 

eof

 

list

 

pid

 

llookup

 

time

 

eval

 

lrange

 

fblocked

 

lsearch

 

gets

 

case

 

lappend

 

proc

 

break

 

variable

 

llength

 

return

 

linsert

 

event

 

error

 

catch

 

call

 

clock

 

info

 

split

 

array

 

if

 

concat

 

join

 

lreplace

 

fcopy

 

global

 

switch

 

update

 

close

 

for

 

append

 

format

 

read

 

package

 

set

 

htonl

 

binary

 

namespace

 

scan

 

trace

 

seek

 

while

 

after

 

flush

 

vwait

 

uplevel

 

continue

 

foreach

 

lset

 

rename

fileevent

 

regexp

 

crc32

 

upvar

 

unset

 

expr

 

regsub

 

interp

 

puts

 

incr

 

lindex

 

lsort

 

string

 

Hi Philippe,

keep in mind that the list above is also containing certain TCL commands (e.g. [interp], [pid], etc.) which are still disallowed by LTMs iRule syntax checking which is enforced during iRule savings. Those commands would require special iRule codings techniques to not expose those commands during iRule savings.

E.g.:

The iRule below wont save:

when RULE_INIT {
    log local0.debug "The PID of the TMM[TMM::cmp_unit] process is: [pid]"
}

The iRule below will work fine:

when RULE_INIT {
    set cmd {
        log local0.debug "The PID of the TMM[TMM::cmp_unit] process is: [pid]"
    }
    eval $cmd
}
